How to get datasets schema with field descriptions

I am looking for a way to extract the schema of my datasets including the description of each field. 

I have GOV_Dataset-schemas (from Domo Governance Datasets) installed, so it partially solve my need.

Following I describe the unsolved part.

I have a data set with three columns:

dataset1  with a description of ‘datase1_description’ (description included with edit name and description in Domo datasets screen)

and columns (description included via data tab, schema icon, description column)

• colum1 type text  with description of ‘column1_description’
• colum2 type number with description of ‘column2_description’
• colum3 type text with description of ‘column3_description’

In GOV_Dataset-schemas I can find three rows for dataset1:

• dataset1 column1 text dataset1_description
• dataset1 column2 number dataset1_description
• dataset1 column3 text dataset1_description

I would be happier if  GOV_Dataset-schemas would give me

• dataset1 column1 text column1_description
• dataset1 column2 number column2_description
• dataset1 column3 text column3_description

Please if anyone knows of any other way to extract datasets scheme with custom description for each field I would appreciate the help.
